Hi, I'm new to UNITY. I was following your 3D platform tutorial and Unity was running smoothly.

However, after I have finished the tutorial I have downloaded several files from your community forums. Everything was running ok until I have opened destructable buildings project or something like that.

Since then no matter what I do, Unity starts with a black window "importing package".

I have tried holding alt and selecting different projects, I have removed all projects, I have reinstalled UNITY several times etc. I have done literally everything imo except cleaning registry / reintalling Windows but UNITY still starts with this stupid window and utilizing one core to 100% and eventually crashing.

What can I do with this? I'd love to continue to work with Unity but this drives me crazy.

EDIT: 100% core utilization and uses 3 GB of ram...

Thanks, yetti
